TECHNICAL FIELD

The present invention relates to cleaning methods. More particularly, the invention relates to a method of improving air quality and reducing the risk of healthcare-associated infections utilizing a cleaning cart with a vacuum cleaning apparatus.

BACKGROUND

Traditional methods for cleaning a patient's area in a medical facility include dry mopping and dusting. Such methods can disperse dust particulates throughout the patient's environment, decreasing air quality. The dust particulates also resettle and contaminate surfaces thought to be clean. Airborne dust could also be breathed by the patient, leading to infections and lowering health quality. Traditional cleaning methods have also included mopping floors using a bucket that is moved from room to room without changing or refreshing the cleaning solution. This approach can lead to cross contamination of bacteria from one room to the next.

SUMMARY

The present invention solves the above-described problems and provides a distinct advance in the art of cleaning methods. More particularly, the invention provides a cleaning method that utilizes a cleaning cart equipped with a vacuum cleaning apparatus. In addition, cleanliness is improved and contamination is reduced by the single-use techniques of the invention.

One embodiment of the present invention is a method of improving air quality and reducing healthcare-associated infections performed by a cleaning personnel in a patient area including a patient room, a patient restroom, and a floor area that includes the steps of: equipping a cleaning cart with a plurality of single-use microfiber cloths and a plurality of microfiber mops, wherein the cleaning cart includes a vacuum cleaning apparatus with an extensible vacuum hose and a plurality of attachments; positioning the cleaning cart outside of an occupied patient room; putting a first pair of gloves on the hands of the cleaning personnel; extending the vacuum hose into the patient room; vacuuming the above-floor surfaces with a first attachment; vacuuming the floor area with a second attachment; dipping the first attachment in a bucket filled with a first disinfectant solution; disinfecting the surfaces that a patient may contact with a first microfiber cloth soaked in a second disinfectant solution; cleaning at least one bathroom fixture with a second microfiber cloth soaked in the second disinfectant solution; removing the first pair of gloves from the hands of the cleaning personnel; washing the hands of the cleaning personnel; putting a second pair of gloves on the hands of the cleaning personnel; mopping the floor area including the floor area of the patient restroom with a microfiber mop charged with a neutral cleaner; and placing the microfiber mop in a plastic bag.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The following detailed description of the invention references the accompanying drawings that illustrate specific embodiments in which the invention can be practiced. The embodiments are intended to describe aspects of the invention in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments can be utilized and changes can be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense. The scope of the present invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled.

In this description, references to “one embodiment”, “an embodiment”, or “embodiments” mean that the feature or features being referred to are included in at least one embodiment of the technology. Separate references to “one embodiment”, “an embodiment”, or “embodiments” in this description do not necessarily refer to the same embodiment and are also not mutually exclusive unless so stated and/or except as will be readily apparent to those skilled in the art from the description. For example, a feature, structure, act, etc. described in one embodiment may also be included in other embodiments, but is not necessarily included. Thus, the present technology can include a variety of combinations and/or integrations of the embodiments described herein.

As shown in FIG. 1 and FIG. 2, the present invention is preferably implemented utilizing equipment such as a cleaning cart 10 with a vacuum cleaning apparatus 12, buckets 14 positioned on or within the cart 10, a plurality of single-use cloths 16, a plurality of single-use mops 18, and a mobile trash apparatus 20. As discussed in more detail below, the equipment including the cart 10 and the wheeled trash barrel is utilized by a plurality of team members to clean a patient area, including a patient room, bathroom, and floor area. However, the various embodiments of the present invention may be utilized to clean any area.

The vacuum cart 10 is preferably a Cartmaster Total Environment Cleaning System manufactured by M.D. Manufacturing, Inc. of Bakersfield, Calif. However, the vacuum cart 10 may comprise any mobile vacuum elements, preferably with HEPA filtering. For example, in some embodiments the vacuum cart 10 may comprise a conventional wheeled cart having a HEPA filtered vacuum positioned thereon. The vacuum cleaning cart 10 and cleaning cart 12 also preferably includes buckets 14 that contain cleaning solution in which to soak single-use cloths 16 and microfiber mops 18. The buckets 14 may be integrally formed within the cart 10 or be discrete elements that are removably transported on or within the cart 10. The cleaning solution could include a disinfectant such as bleach or a similar germicidal solution.

The mobile cleaning equipment has been described above as preferably including three discrete elements—the vacuum cart 10, the supply cart 12, and the mobile trash apparatus 20. However, in some embodiments, the carts 10, 12 and apparatus 20 may be combined into any combination of carts, including a single cart including vacuum, cleaning, and trash elements. For example, as shown in FIG. 2, the vacuum cart 10 may include the buckets 14 and other cleaning supplies such that use of the supply cart 12 is not required. In another alternative embodiment, the supply cart 12 may be equipped with both a vacuum apparatus and a trash receptacle.

The single-use cloths 16 are preferably microfiber cleaning cloths available from Newell Rubbermaid Inc. in Atlanta, Ga., but may include any microfiber or lint-free wipes that have absorbency and strength when wet to allow for intense cleaning. The microfiber cloths are preferably launderable and reusable and can be hand or machine washed and dried at low temperature between 500 and 1000 times.

The single-use mops 18 are preferably made from Newell Rubbermaid Inc. in Atlanta, Ga., but may include any microfiber-type mops that are capable of being treated with a disinfectant. Microfiber mops not only are cheaper to utilize than traditional string mops because they require less water and cleaning or disinfecting solution, but they also offer better cleaning because they can get into crevices and along baseboards where traditional mops have trouble. Microfiber mops also offer the option of being launderable and reusable. One microfiber mop head can be used to mop the floor of one patient area and then discarded into a special bag or compartment in the cleaning cart. Another microfiber mop head can be installed on the mop handle to mop the next patient area. At the end of the shift, all the used mop heads can be washed in traditional laundry detergent and dried at low temperature for reusage during the next shift. The mop heads can be used repeatedly in this fashion between 100 and 500 times.

The mobile trash apparatus 20 is preferably a 32-gallon round container, Model #2632WH, mounted or coupled with a dolly, Model #2640, both manufactured by Newell Rubbermaid Inc. in Atlanta, Ga., but may include any container capable of holding trash that is mobile or can be adapted to a dolly or the like.

Steps 100-106 shown in FIG. 4 generally illustrate a method operable to be performed by various embodiments of the present invention. Steps 100-106 generally include: creating a plurality of team members, referenced at step 100; assigning team member duties, referenced at step 102; cleaning according to the assigned duties, referenced at step 104; and reassigning team member duties, referenced at step 106.

In step 100, a cleaning team is created with a plurality of members. The number of team members can vary from two to three, however, three team members is the preferred embodiment. Two team members will require more time to complete the tasks. Three team members are preferable because the tasks to be assigned can easily be divided into threes, allowing many of the tasks to be performed simultaneously. As a result, for a three-member team, the tasks are readily rotated and can be completed in an efficient and effective manner. As shown in FIG. 3, the various team members preferably include a first team member P1, a second team member P2, and a third team member P3.

In step 102, the individual team members are assigned specific tasks to perform. The first and second team members P1, P2 are assigned the task of moving through the patient area 40 to remove trash. Specifically, the first and second team members P1, P2 also are assigned the task of scanning all floor areas 32 for large debris that may block or interfere with the cart 10 and vacuum apparatus 12. The first and second team members P1, P2 preferably place removed trash and debris in the mobile trash apparatus 20 for easy transport and disposal. The third team member P3 is assigned the task of vacuuming the floor area utilizing the vacuum apparatus 12 after the debris are removed from the floor area. The first team member P1 is assigned the task of damp cleaning the patient area 40 with single-use cloths 16, which are preferably discarded after cleaning a single patient area into a separate bag, located in the cart 10, and laundered later. The first team member P1 also mops the floor area 32 with a microfiber mop 18, which is discarded after mopping the floor area of a single patient area into a separate bag, within the cart 10, and laundered later. The second team member P2 repeats the same set of tasks as team member P1, but in the next assigned patient area.

While the preferable assignments for step 102 are discussed above, other combinations and variations are possible. For example, first and third team members may be assigned the task of removing debris from the floor area, while the second team member is assigned to vacuum the floor. Other assignment combinations are also possible.

In step 104, the patient area 40 is cleaned according to the tasks assigned in step 102. For example, as shown in FIG. 3, the first team member P1 cleans the patient's room 30 of the patient area 40 with one or more disinfected cloths 16 obtained from the cart 10 and mops all floor areas 32 with the damp, microfiber mop 18. The second team member P2 repeats the same tasks as P1 in the next assigned patient area. The third team member P3 vacuums the floor area 32 with the vacuum cleaning apparatus 12. Any debris encountered can be disposed of in the mobile trash apparatus 20. In some embodiments, the second and third team members P2 and P3 may mop the floor area 32 utilizing any equipment and the first team member P1 may damp clean the patient area 40 with any equipment.

In step 106, the team members rotate tasks after a given period of time in order to avoid boredom and fatigue. The preferable period of time is approximately thirty minutes. For instance, after about thirty minutes, the third team member P3 will perform the first team member's P1 tasks, the first team member P1 will perform the second team member's P2 tasks, and the second team member P2 will perform the third team member's P3 tasks. The rotation continues on the given schedule as long as the team is active. As should be appreciated, the tasks may be rotated after any interval to increase team member efficiency and productivity.

It is known that medical facility patient discharge volume increases about 11:00 am. All patient areas in which the patient will continue to stay should be cleaned by 11:30 am. At this time, the team members finish cleaning the patient area they currently working on. Once finished, they move to a patient area where the patient has recently been discharged and they clean the patient area, performing the steps discussed above. The team members continue cleaning the areas where patients have been discharged until all recently-discharged patient areas have been cleaned. There is no disruption to the workflow, but merely a priority given to those areas where patients have recently been discharged. As a result, beds are available sooner for the admission of a new patient.

A second embodiment of the present invention includes a method 200 of improving air quality and reducing healthcare-associated infections in a patient area. The method may be performed by one or more team members P1, P2, P3. The method 200 may utilize the cleaning cart 100 of FIG. 5, or the cleaning cart 110 of FIGS. 14-15. The method 200 may further utilize the buckets 14, the single-use microfiber cloths 16, the single-use microfiber mops 18, and the mobile trash apparatus 20, described in connection with the first embodiment of the invention.

The method 200 may be developed, generated, or programmed using a computer 112, as seen in FIG. 5. The computer 112 may include a palmtop computer, a notebook computer, a laptop computer, a desktop computer, a workstation, a tablet computer, handheld electronic devices such as a cell phone or personal digital assistant, and the like. The computer 112 may include one or more of the following: a processor, a microprocessor, a microcontroller, a field programmable gate array (FPGA), and the like. The computer may also include memory elements that may be considered a “computer-readable storage medium”, such as read-only memory (ROM), random-access memory (RAM), hard-disk drives. The computer 112 may also be able to read other computer-readable storage media, such as compact discs (CDs), digital video discs (DVDs), Blu-Ray™ discs, flash memory, and the like.

The cleaning cart 100, 110 may include a vacuum cleaning apparatus 114, a shell 116, a lid 118, a first frame member 120, a second frame member 122, a hose reel mechanism assembly 124, a rear axle 126, a plurality of brackets 128, and a hook 130. An exemplary cleaning cart 100, 110 may be the XRO1, XRO2, or XRO2.2, manufactured by M.D. Manufacturing, Inc. of Bakersfield, Calif.

The vacuum cleaning apparatus 114 may include components that create suction by which dust, debris, and small particles are removed from surfaces. The suction enables a high-level of removal of even the smallest particles of dust, dirt and particle removal that can be the source of certain nosocomial infections, such as Aspergillus. Nocosomial infections are also known as hospital acquired infections and can be caused by bacteria, viruses, fungi, and parasites. Known nosocomial infections include those caused by Gram-positive cocci (e.g., Clostridium), Tuberculosis bacteria, varicella zoster virus, influenza virus, Aspergillus, Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, Aeromonas hydrophilia, and Legionella pneumophila) Mycobacteria, Staphylococcus aureus, Methicillin resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, Acinetobacter baumannii, Stenotrophomonas maltophilia, Clostridium difficile, Vancomycin-resistant Enterococcus (VRE), enterovirus, and Candida albicans.

The vacuum cleaning apparatus 114 may also include a filtration system 132 positioned at least partially on the shell 116 at the rear of the cleaning cart 100, 110. The filtration system 132 may include four stages. In some embodiments, the filtration system 132 is HEPA certified. In other embodiments, the filtration system 132 is ultra-low particulate air (ULPA) certified (i.e., capable of removing 99.999% of particles having sizes of 0.12 micron or greater). The filtration system 132 may also capture dust that is generated from a motor (not shown) that generates the suction for the vacuum cleaning apparatus 114.

A vacuum cleaning apparatus 114 this powerful would normally generate too much heat to be enclosed within the cleaning cart 100, 110 structure. The vacuum cleaning apparatus 114 and the cleaning cart 100, 110 have been specially engineered to reduce heat emanation and avoid overheating of the cleaning cart 100, 110 and the vacuum cleaning apparatus 114.

The vacuum cleaning apparatus 114 may further include a noise dampening system, such as the system disclosed in U.S. Pat. No. 6,804,857, issued Oct. 19, 2004, which is incorporated by reference in its entirety into the present application. The noise dampening system may operate by using suction to pull noise generated from a vacuum motor back into the motor. The noise dampening system may allow the vacuum cleaning apparatus 114 to operate while generating approximately 53 decibels of sound pressure level.

In certain embodiments, the vacuum cleaning apparatus may include an improved power unit for a vacuum cleaner including a canister having a sidewall, a top and a bottom, an upper interior hollow compartment housing a removable dirt and dust collection receptacle and a lower interior hollow compartment which houses at least one motor and armature, with the at least one motor emitting noise when the at least one motor is turned on, the improvement comprising: (a) bracket means mounting said at least one motor into said lower interior compartment which forms a negative pressured plenum chamber, where said at least one motor is spaced apart from said bottom such that said armature is extending upwardly therefrom for permitting suction air to enter thereto; (b) exhaust means in said sidewall to permit hot air exhaust and noise flow from said at least one motor to exit said negative pressured plenum chamber; (c) a motor exhaust horn extending into said negative pressured plenum chamber and connected to said exhaust means; (d) air intake means in said sidewall to permit said suction air to enter said canister; and (e) said suction air flows into said upper compartment and into said negative pressured plenum chamber, where said suction air becomes cooling air and noise flow which in turn flow around said at least one motor and into a motor opening located adjacent to said bottom of said canister and into said motor exhaust horn and out through said exhaust means, thereby substantially reducing the noise level generated by said at least one motor while at the same time cooling said at least one motor, the noise that radiates from said at least one motor continually sucked back into said at least one motor, and thereby the noise is bent by using suction so that the noise is muffled by being pulled back into said at least one motor; whereby said negative pressured plenum chamber reduces the noise level emitted from said at least one motor while at the same time cooling said at least one motor. In other embodiments, the exhaust means of the power unit includes at least one exhaust port located in said sidewall and extending into said negative pressured plenum chamber. In other embodiments, the air intake means of the power unit includes at least one intake port located in said sidewall and extending into said upper interior compartment. In still other embodiments, the exhaust means of the power unit comes out of said motor and extends through said negative pressure plenum chamber and extends out of said sidewall.

In addition, the vacuum cleaning apparatus 114 may include a vacuum hose 134, a first attachment 136, and a second attachment 138. The vacuum hose 134 may be extensible from the cleaning cart 100, 110, with a proximal end coupled to thereto and an opposing distal end, and may be up to 30 feet in length. The vacuum hose 134 may be manufactured from a strengthened, crushproof material and coated with a microbiostatic agent, such as the Microbe Shield®, manufactured by Aegis Environments of Midland, Mich. In various embodiments, the vacuum hose 134 may be colored orange or a similar bright color to increase the visibility of the vacuum hose 134 for the cleaning personnel or others to avoid tripping over the vacuum hose 134. The first attachment 136 may be suitable for vacuuming non-floor surfaces, such as the horizontal surfaces of tables, stands, equipment, televisions, monitors, light diffusers, vents, window sills, radiators, and other surfaces in a medical facility patient room that may collect dust. The first attachment 136 may include a dusting brush which may include an oval or round shape. The second attachment 138 may be suitable for vacuuming floor surfaces and may include a wide, flat opening for removing dust and debris. Both the first attachment 136 and the second attachment 138 may be removably attached to the distal end of the vacuum hose 134.

The vacuum cleaning apparatus 114 may include additional removable attachments, such as an extension tube 140, a crevice tool 142, a secondary floor tool 144, and a secondary dust brush 146, as are commonly known.

The shell 116, shown in FIG. 6, may include front 148, back 150, left 152, and right 154 upright sidewalls. The sidewalls 148, 150, 152, 154 may be manufactured from hardened or strengthened plastic and may support or retain accessories for the vacuum cleaning apparatus 114 or general cleaning supplies. The shell 116 may couple with a frame 156 of the cleaning cart 100, 110. The shell 116 may further include sound insulation properties to further reduce noise generated by the vacuum cleaning apparatus 114.

The lid 118, shown in FIG. 7, may be generally planar and roughly rectangular in shape and may include an arcuate cutout 158 along one edge to facilitate opening or positioning of the lid 118. The lid 118 may be manufactured from plastic, such as PVC. The lid 118 may be positioned on top of the shell 116.

The first frame member 120 and the second frame member 122, shown in FIG. 8, may be generally elongated with various features such as cutouts, holes, flanged or flared portions, and the like. The first frame member 120 and the second frame member 122 may generally adapt or retain the shell 116 to the frame 156.

The hose reel mechanism assembly 124, shown in FIG. 9, may include first 160 and second 162 spaced-apart and opposing sidewalls, and first 164, second 166, and third 168 spools. The spools 164, 166, 168 may be positioned between the first and second sidewalls 160, 162 and may retain and/or automatically reel in the vacuum hose 134. The hose reel mechanism assembly 124 may be positioned within the shell 116.

The rear axle 126, shown in FIG. 10, may include an elongated rod 170 and a pair of mounting members 172. The rod 170 may be rigidly attached to the mounting members 172 and may be rotatably coupled with rear wheels 174 of the cleaning cart 100, 110. The mounting members 172 may be attached to the bottom of the shell 116, thereby holding the rear wheels 174 in a fixed orientation.

The brackets 128, shown in FIG. 11, may be generally elongated with bends along the longitudinal axis to create an offset and may include a plurality of holes for mounting. The brackets 128 may be manufactured from metal and may be positioned on the shell 116 to hold linens or a trash receptacle.

The hook 130, shown in FIG. 11, is similar to the brackets 128 and may be generally elongated with bends along the longitudinal axis to create an offset and may include a plurality of holes for mounting. The hook 130 may be manufactured from metal and may be positioned on the shell 116 to hold a power cord or accessories.

At least a portion of the steps of the method 200 for improving air quality and reducing healthcare-associated infections performed by a cleaning personnel in a patient area including a patient room, a patient restroom, and a floor area, in accordance with various embodiments of the present invention, is shown in FIG. 12. The steps may be performed in the order as shown in FIG. 12, or they may be performed in a different order. Furthermore, some steps may be performed concurrently as opposed to sequentially. In addition, some steps may be optional or altered.

Referring to step 201, a cleaning cart 10 is equipped with a plurality of single-use microfiber cloths 16 and a plurality of microfiber mops 18. The cleaning cart 10 may include a vacuum cleaning apparatus 12 with an extensible vacuum hose 134 and a plurality of attachments. The vacuum hose 134 may be coated with a microbiostatic agent. The attachments may include a first attachment 136, such as a dust brush, and a second attachment 138, such as a floor tool.

Referring to step 202, the cleaning cart 10 is positioned outside of an occupied patient room. This helps to minimize the number of foreign objects that are brought into the patient room, thereby reducing the chance of cross contamination. This step also reduces the amount of noise that is generated inside the patient room.

Referring to step 203, the cleaning personnel puts on a first pair of gloves 176.

Referring to step 204, the vacuum hose 134 is extended into the patient room, the above-floor surfaces are vacuumed with a first attachment 136, and the floor area is vacuumed with a second attachment 138. The first attachment 136 may include a dust brush. The second attachment 138 may include a floor tool. The above-floor surfaces may include horizontal surfaces, such as vents, televisions, monitors, light diffusers, radiators, window sills, and the like. The above-floor surfaces may be vacuumed starting near the door to the hallway and continuing around the room systematically until returning to the door.

The floor surfaces may be vacuumed by first moving objects away from the walls and vacuuming along the baseboards in a straight-line motion. Objects may be moved from the rest of the floor. The rest of the floor may be vacuumed using back and forth sweeping motions while keeping the vacuum hose 134 behind the cleaning personnel.

Referring to step 205, the first attachment 136 is dipped in a bucket filled with a first disinfectant solution. The first attachment 136 may be dipped for a few seconds. Afterwards, the first attachment 136 may be allowed to air dry. The first disinfectant solution may include a germicide or bleach.

Referring to step 206, the surfaces that a patient may contact are disinfected with a first microfiber cloth 16 that is soaked in a second disinfectant solution. The surfaces may be generally wiped in order to disinfectant them. The second disinfectant solution may include a germicide.

Referring to step 207, at least one bathroom fixture is cleaned with a second microfiber cloth soaked in the second disinfectant solution. The bathroom fixtures may include faucets, dispensers, grab rails, shower stalls, and the like. The toilet may be wiped last before discarding the second cloth. A bowl mop and toilet cleaner may be used to clean the toilet bowl.

Referring to step 208, the cleaning personnel removes the first pair of gloves 176, washes his or her hands, and puts on a second pair of gloves 176.

Referring to step 209, the floor area is mopped with a microfiber mop 18 charged with a neutral cleaner. The floor area may be mopped starting at a far corner opposite the door to the hallway. The floor along the baseboards may be mopped in a straight line motion. The rest of the floor area may be mopped using a back and forth “S”-type motion. The floor area under furniture and other objects should be mopped as well. The floor area should be mopped in the direction of the door.

Referring to step 210, the microfiber mop 18 is placed in a plastic bag. Other items may be placed in the plastic bag as well. The plastic bag is generally retained with the cleaning cart 100, 110, and the contents of the plastic bag may be cleaned or discarded at the end of a work shift.

A third embodiment of the present invention includes a method 300 of improving air quality and reducing healthcare-associated infections in an isolated patient area. The method 300 may be performed by one or more team members P1, P2, P3. The method 300 may also utilize the same equipment as discussed above for the method 200.

At least a portion of the steps of the method 300 for improving air quality and reducing healthcare-associated infections performed by a cleaning personnel in an isolated patient area including a patient room, a patient restroom, and a floor area is shown in FIG. 13. The steps may be performed in the order as shown in FIG. 13, or they may be performed in a different order. Furthermore, some steps may be performed concurrently as opposed to sequentially. In addition, some steps may be optional or altered.

Referring to step 301, a cleaning cart 10 is equipped with a plurality of single-use microfiber cloths 16 and a plurality of microfiber mops 18.

The attachments may include a first attachment 136, such as a dust brush, and a second attachment 138, such as a floor tool.

Referring to step 302, the cleaning cart 10 is positioned outside of an occupied patient room. This helps to minimize the number of foreign objects that are brought into the patient room, thereby reducing the chance of cross contamination. This step also reduces the amount of noise that is generated inside the patient room.

Referring to step 303, the cleaning personnel puts on a first pair of gloves 176.

Referring to step 304, the vacuum hose 134 is extended into the patient room, the above-floor surfaces are vacuumed with a first attachment 136, and the floor area is vacuumed with a second attachment 138. The first attachment 136 may include a dust brush. The second attachment 138 may include a floor tool. The above-floor surfaces may include horizontal surfaces, such as vents, televisions, monitors, light diffusers, radiators, window sills, and the like. The above-floor surfaces may be vacuumed starting near the door to the hallway and continuing around the room systematically until returning to the door.

The floor surfaces may be vacuumed by first moving objects away from the walls and vacuuming along the baseboards in a straight-line motion. Objects may be moved from the rest of the floor. The rest of the floor may be vacuumed using back and forth sweeping motions while keeping the vacuum hose 134 behind the cleaning personnel.

Referring to step 305, the vacuum hose 134 is wiped with a first microfiber cloth 16 soaked in a first disinfectant solution. The first attachment 136 and the second attachment 138 are placed in a plastic bag. The vacuum hose may be wiped while the cleaning personnel is standing near the door facing the cleaning cart 100, 110. The plastic bag may be placed inside the patient restroom. The first disinfectant solution may include a germicide or bleach.
